That is true. The question is what else does it do. > However looking in the neighborhood of option -s, we see: > > -s, --size > print size of each file, in blocks > > -S sort by file size > > It'd be a good idea to take a look at the code to confirm, but given its > description, it'd make more sense if -f disabled option -S instead of > (or in addition to?) option -s. It would be -S in addition to the -s option. Looking at the code I can also see that it disables --color and -1 too. static enum sort_type const sort_types[] = { sort_none, sort_time, sort_size, sort_extension, sort_version }; ... case 'f': /* Same as enabling -a -U and disabling -l -s. */ ignore_mode = IGNORE_MINIMAL; sort_type = sort_none; sort_type_specified = true; /* disable -l */ if (format == long_format) format = (isatty (STDOUT_FILENO) ? many_per_line : one_per_line); print_block_size = false; /* disable -s */ print_with_color = false; /* disable --color */ break; ... case 's': print_block_size = true; break; ... case 'S': sort_type = sort_size; sort_type_specified = true; break; It may seem strange that this is documented as it is but the documented behavior is required by POSIX. http://www.opengroup.org/onlinepubs/009695399/utilities/ls.html -f Force each argument to be interpreted as a directory and list the name found in each slot. This option shall turn off -l, -t, -s, and -r, and shall turn on -a; the order is the order in which entries appear in the directory. It also has additional behavior too.
